The configuration of a first embodiment of the shoe cleaner 120 can best be seen in FIGS. 3-7, which are, respectively, an enlarged diagrammatic perspective view of the area generally enclosed by the dotted curve identified by ARROW 3 in each of FIGS. 1 and 2 of a first embodiment of the shoe cleaner of the present invention, an enlarged diagrammatic cross sectional view taken along LINE 4-4 in FIG. 3, a reduced diagrammatic top plan view taken generally in the direction of ARROW 5 in FIG. 3, an enlarged diagrammatic side elevational view taken generally in the direction of ARROW 6 in FIG. 3, and, a schematic diagram of the circuitry of the shoe cleaner of the present invention, and as such, will be discussed with reference thereto.

The shoe cleaner 120 comprises an enclosure 126, a brush assembly 127, a track drive 128, and a brush drive 130.

The enclosure 126 is for attaching under the door 22 of the vehicle 24.

The brush assembly 127 is retractably and extendably attached to the enclosure 126.

The track drive 128 is operatively attached to the brush assembly 127 to retract and extend the brush assembly 127 relative to the enclosure 126.

The brush drive 130 is operatively attached to the brush assembly 127 to spin the brush assembly 127.

The enclosure 126 is generally rectangular-parallelepiped-shaped, and has a pair of side walls 132, a back wall 134, a top wall 136, a bottom wall 138, and an open front 140.

The brush assembly 127 comprises at least one brush 142 and a pair of arms 144.

Each brush 142 of the brush assembly 127 is cylindrically-shaped and rotatably mounted between the pair of arms 144 of the brush assembly 127, by an axle 146.

The pair of arms 144 of the brush assembly 127 are retractably and extendably attached to the enclosure 126 so as to allow the at least one brush 142 of the brush assembly 127 to extend from and retract into the enclosure 126.

The track drive 128 comprises a motor 148 and a worm gear 150.

The motor 148 of the track drive 128 is attached in the enclosure 126.

The worm gear 150 of the track drive 128 is operatively attached to the motor 148 of the track drive 128 and to the pair of arms 144 of the brush assembly 127 so as to allow the pair of arms 144 of the brush assembly 127, and the at least one brush 142 of the brush assembly 127 therewith, to extend from the enclosure 126 when the motor 148 of the track drive 128 rotates the worm gear 150 of the track drive 128 in one direction, and to allow the pair of arms 144 of the brush assembly 127, and the at least one brush 142 of the brush assembly 127 therewith, to retract into the enclosure 126 when the motor 148 of the track drive 128 rotates the worm gear 150 of the track drive 128 in the other direction.

The brush drive 130 comprises a motor 152, a drive pulley 154, a driven pulley 156, and a drive belt 158.

The motor 152 of the brush drive 130 is disposed to move with the pair of arms 144 of the brush assembly 127, and has the drive pulley 154 of the brush drive 130 connected thereto to rotate therewith.

The driven pulley 156 of the brush drive 139 is connected to the axle 146 of the brush assembly 127 to rotate therewith.

The drive belt 158 reeves around both the drive pulley 154 of the brush drive 130 and the driven pulley 156 of the brush drive 130 to spin the at least one brush 142 of the brush assembly 127 when the motor 152 of the brush drive 130 is activated.

As shown in FIGS. 6 and 7, the track drive 128 further comprises an extension limit micro-switch 160 and a retraction limit micro-switch 162.

The track drive 128 further comprises one side wall 132 of the enclosure 126 having a through slot 164. The through slot 164 in the one side wall 132 of the enclosure 126 extends longitudinally therealong, and has a forward terminus 166 and a rearward terminus 168.

The extension limit micro-switch 160 of the track drive 128 is disposed on the one side wall 132 of the enclosure 126 and operatively communicates with the forward terminus 166 of the through slot 164 in the one side wall 132 of the enclosure 126.

The retraction limit micro-switch 162 of the track drive 128 is disposed on the one side wall 132 of the enclosure 126 and operatively communicates with the rearward terminus 168 of the through slot 164 in the one side wall 132 of the enclosure 126.

The track drive 128 further comprises a pin 170.

The pin 170 of the track drive 128 extends laterally outwardly from a rearward position of an arm 144 of the brush assembly 127, adjacent the one side wall 132 of the enclosure 126, and freely through the through slot 164 in the one side wall 132 of the enclosure 126.

The brush assembly 127 is extended from the enclosure 126, when the polarity to the motor 148 of the track drive 128 is such that it rotates in one direction, until such time that the pin 170 of the track drive 128 contacts the extension limit micro-switch 160 of the track drive 128 stopping the motor.

The brush assembly 127 is retracted into the enclosure 126, when the polarity to the motor 148 of the track drive 128 is reversed such that it rotates in the other direction, until such time that the pin 170 of the track drive 128 contacts the retraction limit micro-switch 162 of the track drive 128 stopping the motor.

The configuration of a second embodiment of the shoe cleaner 220 can best be seen FIG. 8, which is an enlarged diagrammatic perspective view of the area generally enclosed by the dotted curve identified by ARROW 8 in each of FIGS. 1 and 2 of a second embodiment of the shoe cleaner of the present invention, and as such, will be discussed with reference thereto.

The shoe cleaner 220 is similar to the shoe cleaner 120, but with the at least one brush 242 of the brush assembly 227 being two brushes 242, disposed side-by-side with each other.

The configuration of a third embodiment of the shoe cleaner 320 can best be seen in FIGS. 9-11, which are, respectively, a diagrammatic perspective view of the area generally enclosed by the dotted curve identified by ARROW 9 in each of FIGS. 1 and 2 of a third embodiment of the shoe cleaner of the present invention, a diagrammatic side elevational view taken generally in the direction of ARROW 10 in FIG. 9, and, a diagrammatic perspective view taken generally in the direction of ARROW 11 in FIG. 9, and as such, will be discussed with reference thereto.

The shoe cleaner 320 is similar to the shoe cleaners 120 and 220, but with the addition of the enclosure 326 having a door 372. The door 372 of the enclosure 326 is pivotally attached to the bottom wall 338 of the enclosure 326, and closes the open front 340 of the enclosure 326 when the brush assembly 327 is retracted into the enclosure 326 and opens the open front 340 of the enclosure 326 when the brush assembly 327 is to be extended from the enclosure 326.

The door 372 of the enclosure 326 is operatively connected to the extension limit micro-switch 360 of the track drive 328 and the retraction limit micro-switch 362 of the track drive 328 so as to open when the brush assembly 327 is to be extended from the enclosure 328 and to close when the brush assembly 327 is retracted into the enclosure 328.
